CABLE ANCHOR Filed Dec. 1, 1944 Patented Apr. 17, 1945 proved cable anchor, and in particul'airtlie' 1nveri` tionis :directed to, and `it isfan'object tc provide,

a novel cable'anchor'fordeadeendingf'a cable to j .the cable drum of apowerwinch'or the like.

Anotherobjec't for the invention is! to 4provide a cable anchor which doesnot"reduire'tany'tools forv attachment `.of ;the cable, nor the loosening and retightening of any mechanical clamps; all

' whereby arcable end portion may' be dead-end'lf-IO connected to acca-ble drum quickly and readily..

A further object of this invention is topro? vide a cable. anchorl which-includesin theend `plate of the cable an elongated. circumfer- `entially extending-slot throughsaidplate, a sub-f stantially radial .tohguel'projecting part ,way Y `across said .slotfrom its lowerledge and inter'- mediate its `ends, the space, between the Ireeend of the tongue and the outer edge of the'slotbe-ng of Asuicient extent' to permit of. the passage of the cable through said space, and a laterally outwardly projecting cable retaining lip on said free end of the tongue.

A further object of the invention is to pro-A vide a simple and inexpensive device, and yet one which will be exceedingly eiective for .the

purpose for which it is designed.

These objects are accomplished by means of such structure and relative arrangement of parts aswill fully appear by a perusal of the following specification and'claims. y

In the drawing similar characters of reference indicate corresponding parts in the several views:

Figure 1 is a perspective View of a cable drum embodying the invention; the rear end plate of j the drum being broken away.

Figure 2 is an enlarged, fragmentary elevation of one of the cable anchors as found in a cable drum side plate.

Figure 3 is a cross section on line 3- 3 of Fig. 2. Figure 4 is Va cross-section on line 4-4 of Fig. 2. Referring now more particularly to the characters of reference on the drawing, the numeral l indicates a cable drum of a mechanism such as a power winch; said cable drum including a circular end plate 2.

In the present embodiment the cable drum is illustrated as including two of the cable anchors in end to end relation, but as such anchors are identical, a description of yone will suice.

Each cable anchor comprises an elongated slot 3 formed in the end plate 2 between the inner and outer edges of the latter; said slot extending circumferentially and being generally concentric to the axis of the cable drum I.

A substantiallyk radial toiigluelv 4 projects.. part way-across the slot-Bfrorn theloweriedgefland centrally between the! en'ds *of vthe .latterl. The

Aspace betweenl Ithef freei'e'n'dlof the. tongue 4: rand k the outeredge'of the" slot.y 3, which .space yis-1in- `dicated at 5, is of sufficient extentzradiallyzof the cable drum'to lpermit the'passage of I the cable 6 therethrough. f Y `f 'f 1 At its freeend thetongue 4 includes-ta laterally outwardly projectinglcable retaining. lip 1'.

The vabove described cableanchor isusedto dead-end the cable'i to'tlie cable drum'l inthe Vfollowing manner:l

`Theable :6 adjacent oneend thereoi'is-manipulated toform a loopiwhi'ch'; isi-projected .from the inner side-'offrplate 2' throughthe space or :gap

5,'and'is-'then hooked beneath: thelipl on tongue 4. As so engaged in the slotjithecablespasses,

from the inner sidecf plate z, @inwardly through f -on'ee'rid offsaid s'loil :aboutfthetongue' 4 beneath the lip 1 and then projects inwardly through the slot at its opposite end. The cable is then tightened, which tends to straighten the portion yof the same engaged in' slot 3, with the result that the cable is frictionally bound against the outside of the tongue and against the plate 2 at opposite ends of the slot 3. As so frictio-nally bound, the cable is retained against escape from said end plate 2. The distance, circumferentially of the end mate-between each end of the slot and the corresponding side edge vof the tongue 4, is relatively short whereby to produce the necessary angle or bendy of the corresponding part of cable 6 to bind the latter 'as described.

With the above described cable anchor it will be seen that a cable may be anchored to the drum lreadily and with a minimum of effort. No tools are required to anchor the cable, for the reason that the device includes no parts, such as clamps, which must be unloosened and retightened, and which is a disadvantageous feature of conventional cable` anchors. Also, by virtue of the fact that the cable is formed entirely in one of the` end plates of the drum, the cable may be wound onto said drum without interference by the anchoring means.

From the foregoing description it will be readily seen that there has been produced such a device as substantially fullls the objects of the inven tion as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device,

still in practice such deviations from such detail may be resorted to as do not form a departure ferential slot cut therethrough, and a rigid tongue f projecting part way across the slot from its inner edge and intermediate its ends, the space between the free end of the tongue and the outer edge] of the slot being of suilcient extent to permit a cable loop to pass through said space for engagement about said tongue from one side of the end plate.

2. A cable anchor for a cable drum including ils ferential slot cut therethrough and a rigid tongue projecting part way across the slot from its inner edge and intermediate its ends, the space between the free end of the tongue and the outer edge of the slot being of sufcient extent to permit a cable loop to pass through said space for engagement about said tongue from one side of the end plate; said tongue extending substantially radially oi' the drum.

5. A cable anchor for a cable drum including an end plate, said end plate having a circumferential slot cut therethrough, a rigid tongue projecting part way across the slot from its inner edge and intermediate its ends, the space between the free end of the tongue and the outer edge of the f slot being of sufficient extent to permit a cable an end plate, said end plate having a circumferential slot out therethrough, and a rigid tongue` projecting part way across the slot from its inner., .Y

edge and intermediate its ends, the space between the free end of the tongue and the outer edge of the slot being of suidcient extent to permit a cable loop to pass through said space for engagement about said tongue from one sideoi the end plate; said slot being substantially concen- 1 tric to the drum axis.

3. A cable anchor for a cable drum including an end plate, said end plate having a circumfer ential slot cut therethrough, and a rigid tongue projecting part way across the slot from its inner edge and intermediate its ends, the space between the free end of the tongue and the outer edge of the slot being of suflcient extent to permit a cable loop to pass through said space `for engagement about said tongue from one side of the end plate; said slot being Vrelatively shortbetween the ends thereof and corresponding side edges of the tongue.

4. A cable anchor for a cable drum including an end plate, said end plate having a circurnA loop to pass through said space for engagement about said tongue from one side of the end plate, and a laterally outwardly projecting cable retaining lip on the free end of the tongue, the cable loop extending beneath said lip when engaged about the tongue.
